A Model of the Mechanical Waves in Curved Bars
(Universitatea "Dunărea de Jos" din Galați, 2007)
The different classical models of the mechanical waves in bars
cover every a single type of the wave, respectively only longitudinal,
transversal, inflexion or torsion wave and only in a rectilinear bar, every
with his ...
Study of Noise Produced by Elevators Inside Buildings
(Universitatea "Dunărea de Jos" din Galați, 2007)
This paper studies the way in which elevators movement produces work
perturbing noises. The studies were made on two types of buildings: a
modern building, with noiseless elevators and another one with old
elevators. ...
Influence of the Road Dislevels Upon the Traction System of the Self-Propelled Machines
(Universitatea "Dunărea de Jos" din Galați, 2007)
The kinematic response is caused by run away about the equipment of the
movement modeled in the mechanic system with degree of freedom. The kinematic
excitation considered produces harmonic formally to the organ axle of ...
The Grinding Charge of Rotary Mills
(Universitatea "dunărea de Jos" din Galați, 2007)
This paper presents the achievemens of grinding charge for the tube mills
with balls.The author shows charactheristic size of grinding media
charge: bulk density, porosity, filling degree. Regarding this last size,the
author ...
All-Purpose Low Frequency Numerical Filter
(Universitatea "Dunărea de Jos" din Galați, 2007)
A real signal is a complex system with mixed components. In
addition to needed components appear unusable components with different
origin, namely noise. The clearance or the reduction of the unwanted
components is ...
3D Modelling a Spur Gearing with Solid Edge
(Universitatea "Dunărea de Jos' din Galați, 2006)
The software Solid Edge software is a useful 3D computer aided design (CAD)
running under Windows. The commands and icons of Solid Edge software offer the
possibility to design various solids. In this paper are presented ...
The Idenfication (In Simulink) of an Elastic
(Universitatea "Dunărea de Jos" din Galați, 2007)
In this paper is realized the identification of an elastic system with one degree of
freedom, for which we experimentally pick up (in SIMULINK) the resonance curve.
The system parameters (m, c, k) are determined using ...
Some Considerations of using Virtual Reality in the Training Process Specific to Disciplines of Applied Mechanics
(Universitatea "Dunărea de Jos" din Galați, 2009)
In this paper, we first discuss issues regarding the training in mechanical design
using CAD software to develop the geometric model of the components, the
simulation possibilities of functioning in the case of the model ...
Experimental Testes in Oven Equipped with Burner Sonoc Generator Gazodynamic
(Universitatea "Dunărea de Jos" din Galați, 2015)
Burning is the oldest technology of humanity, and it has been used for more than a million years.Combustion plants must be as efficient, to achieve a more complete combustion, to have a higher efficiency and an emission ...
Experimental Study of the Air-Jet Stem Generator
(Universitatea "Dunărea de Jos" din Galați, 2015)
Applications of sound and ultrasound air-jet stem generators became of great interest in heat and power engineering, in environmental protection, in the production of heat insulating material, extraction of poor uranium ...
